One advantage to using biomaRt is that annotations are available for each gene so descriptions can be returned in the differential expression analysis alongside statistics for each gene. The processing of input files proceeds with reducing multiple sources and multiple targets (gene identifiers) to generate unique edges. An R script was designed to pseudo-align, using Kallisto, batches of trimmed mRNA reads (according to the sample processing configuration file), and to test, using Sleuth, for differentially expressed genes. _igraph: Network Analysis and Visualization in R_. The scalability, and function coverage of these six software packages are assessed and compared. https://doi.org/10.1093/bioinformatics/btp352. 8,
We still consider igraph as a child project. Empirical results show that these six software packages are complementary rather than competitive and the difference on the scalability among theseSix software packages may be attributed to the varieties in both of the programming languages and the network representations. Figure2C shows an example of a cluster dendrogram created by the average linkage hierarchical clustering obtained after merging the modules with similar co-expression profiles. Comparisons on statistics of gene expression estimates between a spliced read aligner and a pseudo-aligner can be used to better understand the dynamics of gene expression.
